Description
As a certified reference material (CRM), Salbutamol EP Impurity M meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Salbutamol EP Impurity M (CAS 18910-70-8) is a certified pharmaceutical impurity reference standard with the molecular formula C14H23NO3 and a molecular weight of 253.34 g/mol.
Structurally, Salbutamol EP Impurity M (C14H23NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 253.34 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
